Ways to improve the efficiency with which materials are pulverized in impact centrifugal mills as well as ways of preventing wear of the blades are proposed. The problem is solved using equations that describe the motion of particles on the surface of the rotor in a polar coordinate system. It is discovered that the rate of impact of the particles ...

Questions connected with the determination of the dynamic loads arising in the mobile components of a planetary mill with a gear drive are considered. The influence of the structural and technological parameters on the magnitude of the loads is analyzed. A horizontal planetary mill with external (respectively, internal) spinning of the grinding dru...

The research project puts a focus on stone artefacts (millstones, hone stones, etc.) traded, used and discarded in (the northern parts of) the Roman ‘Civitas Menapiorum’ and its neighbouring regions. This area is formed by the current Belgian provinces of East- and West-Flanders together with the Dutch province of Zeeland and is geologically charac...

This paper presents the design of a new rotational vibration mill. Experimental research of abrasive wear of grinding bodies in the processing of quartz sand was conducted. The influence dependences of varied process parameters on the specific wear of grinding bodies are demonstrated. Besides, the influence dependence of particle size on the specif...

Un corpus de 125 meules et fragments de meules associé à 309 éclats a été mis au jour en 2013 et 2014 lors de la fouille d'un moulin à minerai hydraulique sur le site de Brandes-en-Oisans (France, Isère, Huez). Intégré dans la chaîne opératoire des métaux polymétalliques (plomb, cuivre, argent), l'étape du broyage se place entre le concassage et le...
